Article Synopsis
- The study compared two types of nitrogen-doped 3D graphene (N3DG and N3DG-D) with pristine 3D graphene (P3DG), created using a thermal CVD process at varying carbon precursors and temperatures.
- Various characterization techniques (SEM, Raman, and XPS) were used to analyze the graphene's morphology, structure, and composition, followed by electrochemical tests for lead sensing and Electric Double-Layer Capacitor (EDLC) applications.
- Results showed that defect-rich N3DG-D had the highest current density for lead detection, while N3DG exhibited excellent lead-sensing capability and suitability for EDLC applications, outperforming the other materials in performance.
Carbon nanotube (CNT) hybrid composites were formed by combining a CNT and silicone elastomer solution with Kevlar yarn, Kevlar fabric, and Kevlar veil materials. The integration of a CNT-silicone matrix with Kevlar yarn and fabric materials produced a composite with moderate electrical and thermal conductivity due to CNT fabric combined with the strength of Kevlar fabric or yarn. In the material synthesis, a notable difficulty was that the CNT-silicone did not bond strongly to the Kevlar.
